Roadmap towards Zero Liquid Discharge Studies


According to CPCB, “Zero Liquid discharge (ZLD) refers to the installation of facilities and system which will enable industrial effluent for absolute recycling of permeate and converting solute (dissolved organic and inorganic compounds/salts) into residue in the solid form by adopting a method of concentration and thermal evaporation”.

ZLD helps an industry in eliminating the discharge of waste water into nearby water bodies or on land, by enabling efficient recycling of waste water streams. The institute, as an outcome of the studies conducted at some of the industrial sectors, has outlined an “Action Plan cum Roadmap towards ZLD”. It focuses on the three-pronged approach for developing the roadmap for the Zero Liquid Discharge.

Water cost savings up to Rs. 6 Lakhs per day

Immediate 20%-30% reduction in water use through low cost interventions
Reduction in wastewater generation through recycle and regeneration mechanisms

CII Water Institute has developed a “Roadmap towards ZLD” with comprehensive Action Plan comprising of short term and long term priorities for a textile unit of Aditya Birla Group in the Philippines.
The Institute has signed Memorandum of Understanding with SAIL on developing a roadmap for achieving Zero Liquid Discharge for various integrated Steel Plants across India. It has been working with SAIL in conducting comprehensive water audits across its integrated steel plants and mines.
